"The former Secretary of State, who lies like a dog — a nasty woman — who used her position to violate the Espionage Act, to obstruct justice, to undermine Congress, to undermine the FBI and the Justice Department, who clearly gave secrets to the enemy . . . she just revealed how long it takes from the time the president orders the launching of a nuclear missile to the time its launched," he said on his Friday program, according to Conservative Review.

"And I can assure you, our enemies in Russia, our enemies in China are all meeting trying to formulate potential responses to this," Levin said.

During the debate at the University of Nevada-Las Vegas, Clinton said: "There's about four minutes between the order being given, and the people responsible for launching nuclear weapons to do so.

"That's why 10 people who have had that awesome responsibility have come out and, in an unprecedented way, said they would not trust Donald Trump with the nuclear codes or to have his finger on the nuclear button," Clinton said.

A Clinton campaign aide, however, said that the information did not come from any classified briefings, CNN reports.

Still, Levin said Friday that Clinton "has demonstrated in her public capacity, in her official capacity that she’s irresponsible, that she's dangerous — and that she's nasty."
